--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Can you attach the testcase please, rather than pasting it as a comment. I can't reproduce the note from the example, but whitespace is significant here, and I'm not sure roundtripping through a BZ comment has preserved it. Thanks. That said, it looks like it's giving up, due to a line wider than > LINE_MAP_MAX_COLUMN_NUMBER; the note doesn't seem to consider that case (rather the case of running out of location_t values).
